MULTICAL® 803 & ULTRAFLOW®
6 Connection of power supply
6.1 Mains supply
MULTICAL® 803 is available with supply modules for either 24 VAC/VDC or 230 VAC.
MULTICAL® 803 can be supplied from either 24 VAC/VDC or 230 VAC with cable through the large
cable connection to the left in the connection base. Use connecting cable with an outer diameter
of 4-10 mm and ensure correct cable stripping as well as correct mounting of cable relief. If
connecting to 230 VAC, it is important to make sure that the whole installation complies with
current regulations. Kamstrup A/S can provide a supply cable to connect the mains supply, in the
size 2 x 0.75 mm². The supply cable to the meter must never be protected by a larger fuse than
permitted for any given cable size.
In case of doubt, it is recommended to take advice from an authorised electrician and get an
individual assessment of the execution of the installation in question. In addition, note that work
on fixed installations and any intervention in the fuse box must be carried out by an authorized
electrician only.
For installation in Denmark: See “Installation of mains connected equipment for registration of
consumption” from the Danish National Safety Board.
